The First Systematic Survey of Stellar Halos in High-Inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies
Bojun Tao et al 2026 ApJS 284 31 Analysis of 93 stellar halos detected in a sample of 169 high-inclination galaxies showed that high-mass galaxies have more extended halos and more active merger…
